Specification of Letters Patent.

Application filed May 9, 1912. Serial No. 696,103.

To all whom it may concern Be it known that I. Hsanox A. \IAR'IIN.

a citizen of the Fnited States. residing at Dayton. in the county of Montgomery and State of- Ohio. have invented certain new and useful Improvements in Cash-Registers, of which I declare the following to be a full, clear, and exact description.

This invention relates to sales recording and registering apparatus and among its objects areto provide printing mechanism constructed toprint triplicate records of sales on inserted sales slips, and totalizing mechanism for separately totalizing the amounts of such sales according to departments or. cl es of transactions, and simultaneously tr talize in another totalizer the aggregate of the individual totals.

Another object of the invention, for the purpose of selecting a desiredtotalizer for operation. is to provide means operated through direct connections with depressible keys for adjusting a set of multiple totalizers'to different extents with respect to actuating devices therefor.

Another object of the invention is to provide a novel and useful 'alining device for a multiple totalizer carrying frame. which device serves to aline the frame so that the totalizer which is in the plane of certain actnatingracks will be accurately engaged Y therewith upon 'a rocking movement of the frame, and which alining device remains in engagement with the frame during its rocking movement. I

Another object'of the invention is to provide a differentially adjustable receptacle having a plurality of compartments for receiving stubs in classified order cut from sales slips printed by the machine.

Another object of the invention is to provide improvements in design or cipher eliminating mechanism for the printing mechanism and having the well known function of preventing the printing of ciphers to the left of the highest numeral of any record. but which mechanism is particularly adapted for the elimination of ciphers in that class of printing devices wherein the type 50 carriers are differentially set directly from the position to which they ere set on a preceding operation to a desired new position without first being returned-to a home or zero position.

.\ further ohject of the invention is to ing mechanism.

provide an improved mechanism for controlling total and subtotal printing in the multiple totalizer machine. I

ll'ith these and incidental objects in view. the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in the appended claims, and a pre,

ment total-izers. Fig. 5 is a transverse vertical section taken atthe side of the bank of department keys.

The invention relates to improvements in machines of that general type known as department store registers. Its functions, aside from segregating in classes amounts accumulated. are in most essentials similar to the functions of the cash registers shown in ti patents to Thomas Carroll No. 980.201.'gr; inted January 3rd. 1911. and No. 931.99%, granted September 28th, 1909.

The keyboard and diilerential mechanism and the main totalizer employed in the present invention are in design similar to such devices as appear in the copending application for patent of Kettering and Chryst. cash register. No. 151,116, filed September 2nd, 1908. Also the arrangement of department totalizers is as shown in a copending application of Kettering and Chryst, registering mechanism,

As noted in the above objects, the present invention relates more particularly to multiple totalizer positioning mechanism and to a difierentially adjustable sales slip stub receptacle by which the stubs of sales slips printed on, are classified in compartments of the receptacle.

Incidentally the invention relates to improvements in construction which facilitate the assembling and dismantling, of the machine. A

The principal mechanical devices employed in the present invention are a driving mechanism, a differential mechanism,

totalizing devices andslip printing mechanism Which are set by said differential mechanism, and a keyboard comprising value keys, department keys and a inanually adjustable lever. The value keys control the differential mechanism for operating the totalizing devices and setting type carriers; the department keys control part of the differential mechann n "for the selecthe total printing and reset lever has conserted sales slips.

the

The gear l is fast to'a driving shaft 8 to which is fastened a shouldered stop disk 9 normally engaged by :upawl 1O pivoted on a rod 11 and which may be rocked to release the driving mechanism through. connections operated by the depression of a department key, as explained farther on. Thus on the depression of a department key the drive shafts 1 and 8 may be rotated by operation of ,crank 7, two revolutions of which are required to effect the necessary single rotation of the drive shafts on each operation of the .riachine.

Keg board.The keyboard :omprises a plurality of denominational banks of value keys 33 (Fig. 2) as required by the predetermined capacity of the machine. a single bank of department keys 21 (Fig. and a manually adjustable lever 131 (Fig. 9) for controlling totalizing and subtotalizing operations.

The value keys 33. as shown in F ig. 2, control the differential mechanism in its movement and have connections for releasing for operation such elements 01 the differential mechanism as are required. These keys are depressible against the action of springs surrounding their shanks and have inclined edges 258 which, on their downward movement. engage pins 257 on key detent plates hung from pivot pins 36 by arms 3l3'and 3H. The detent plates 256 carry pins 3561 for engaging shoulders on bell crank zero stops 37 for differential segments 39. The zero stops 37 have lugs 371 normally in the path of shoulders 38 of segments 39. \Vhen a value key is depressed its inclined edge 25S engages a pin 257 thus rocking the plate 256 downwardly and causing its pin 3561 to engage the forwardly'extending shoulder on the zero stop 37 rocking the stop out of the path of a corresponding segment 39. In this manner the segment is made free to operate upon operation of the driving mechanism.

To look depressed value keys in their inner positions detent plates 32 are provided on the opposite side of the keys from plate 256, which are also hung from pivot pins. 36by a pair of arms similar to arms 313 and 314 in the manner of plates 256.

r The detents 32 are provided .with pins 3% tion for operation of department totalizersn tents 32 are pivoted is forked at its rear end to engage a rod 312 carried by arms 311 opposite notches 35 in the keys and each Q arml313 to which the lower ends of the de- 1 2 causing pins to enter the notches 35 of sitioning the department totalizer frame 110 (Fig. 1).

The department keys 21 (Fig. 5) are depressible against the action of springs 186 extended bet-ween pins on the keys and pins on the key frames. and each key is provided with a pin 22 for cotiperating with slots in plates 19 hung from pins 2300 on the key frame by arms 23. At its upper end the plate 19 1s proyided with a notch in which may enter a laterally extending lug 17 on an arm 16 fast to a frame 29 loose on a shaft 11 (Fig; 2). Also rigid with frame 29 is n .arm 13 (Fig. 1). Pivoted to arm 13 is a link 12 connecting it to the stop pawl 10 coacting with shouldered disk 9 fast to drive shaft 8. When a department key 20 is dejp'ressed its pin 22 through engaging the inclined edge of one. of slots 20 in plate 19 forces the plate upward, thus causing its edge 18 to pass away from lug 17 on arm 16 and its notch 25 to come opposite the lug. Arm 16 then rocks upwardly, its lug 17 entering the notch 25 and thereby locking the depressed key in its depressed position as plate 19 cannot then return to normal position. The arm 16 is" ca-used to thus rock by a spring 15 (Fig. 1) extended between a pin on link 12 and a pin on the side frame of the machine. This spring urges the link for wardly. thus, through arm 13. rocking frame 29 (Fig. 2;) in a clockwise direction. and as this frame is rigid with arm 16 the latter is rocked in a clockwise direction. The forward movement of link 12 (Fig. 1) rocks stop pawl 10 around its pivot 11 so that the pawl is disengaged from disk 9. Tu, this manner the driying mechanism of the machine is released for operation.

The rocking movement of arm 16 (Fig. 5) as above described, is employed to rock rod 31 for the purpose of locking the value keys from manipulation. For this purpose a link 30 pivoted to the arm 16 (Fig. 5) connects said arm with a rearward extension of one of the arms 311 fast to rod 31. the function of which was previously described.

' The rocking movement of arm 16. by forcing the link 36 downwardly. effects the required rocking of shaft 31 to lock the value keys.

in order that the department keys may differentially position the'department'totali zer carrying frame 11.6 (Fig. 4-). the @1118 22 on the department keys (Fig. 5) also cooperate with a plate 161 best shown in Fig. 7 and having an inclined edge 165 and two inclined slots 166 and 167. The pitch of the inclines is progressive. The plate 161 is supported by arms 162 and 163 hung from pivot pins 161 on the key frame. The lower arm 163 has pivoted thereto a link 168 (Figs. 5, 7 and 8) connecting the arm with a segment gear 170 pivoted to a tie bar 171 connecting the machine frames. The segment gear 170' has teeth meshing with teeth 172 on a rack 173 secured to the forwardly eX- tending arm 174 of the'totalizer frame 110 (Fig. 4;).

The uppermost department key (Fig. 5)

has its pin 22 in such position as not to engage plate 161 when the key is depressed. The second key from the top. by its pin 22 engaging slot 167 when depressed, causes plate 161'to be moved upward slightly. The third key from the top would cause the plate to move upward two units. while the lowest key, by engaging incline 16 forces the plate upward three units. In this manner a differential movement may be communicated to link 16S and through this link cause segment gear 170 to be rocked diiferentially and thereby. through the rack 173. differentially position the totalizer frame 110 along guide rails 157. However, if the uppermost department key 21 is depressed. as it has no effect on plate 161. the totalizer carrying frame 110 will be permitted to remain .in its normal position.

For the purpose of releasing depressed keys at the end of an operation of the machine shaft 1 (Fig. 2) has fast thereon a cam 26 cooperating with a roller 27 on a pitman 28 which is pivoted at its upper end to frame 29 and atits lower end is forked over shaft 1 to be guided thereby. When pitman 28 is lifted by cam 26 frame 29 rocks in a counterclock\\ise direction withdrawing flange 17 of pawl 16 (Fig. 5) from notch 25 in the department key detent 1 and also permitting link 30 to return to normal position under spring action and thereby. through rod 31 (Fig. 2) and arms 311 carried thereby and the rod 312. forces the key locking detents 32 for the value keys down ward so that their pins 3+ are carried out of the notches in the keys and thus permit the keys to return to their outer position.

To insure the release of the value keys on the downward movement of detents 32. it is also necessary to more the key detents 256 downwardly so that their pins 257 are diS- engaged from depressed keys. For this purpose frame is loosely pi oted on shaft 11 in position to engage the upper ends of the detents 256.. tween frame 185 and frame 29. From this construction it follows that when frame 29 is rocked in a counter-clockwise direction the Springs 181 are interposed bea v Simultaneously with the release of the keys the stop pawl (Fig. 1) is returned into position to be engaged by disk 9 and thereby stop the driving mechanism of the machine at the proper point in condition to begin another operation. The arm 13 being rigid with. frame 29 the return rocking movement of the frame causes link 12 to move to the rightv and thereby permit pawl 10 to move to stopping position under the action of its spring.

The keyboard is also provided with a lever 131 (Fig. 9) for controlling total and subtotal printing operations. The lever 131 has five different positions, the central one in which it is shown in. Fig. 9, being its normal position in which position it permits the machine to operate in a normal manner for accomplishing addition. If the lever is shifted one step above this position it will control the machine for printing a total from the department totaliZe-rs, and if it is shifted one step below its central position it will control the machine for print ing a total from ,the main totalizer. If the lever is shifted to its uppermost position then on the operation of the machine a subtotal will be printed from one of the department totalizers, whereas if the lever is shifted to its lowest position a subtotal will be printed from the main totalizer. Another function of this lever is to prevent depression of value keys when the lever is. outof its normal position so that the keys may not interfere with total and subtotal printing operations. The lever 131 is pivoted on a rod 61 fixed in'the machine frames and is rigid with an arm 217 the surface 218 of which is formed to co-act with a roller 2&9 on a pitman 250 forked to straddle rod 61 to be guided'thereby at its lower end and pivoted at its upper end to a short arm 251 fixed to shaft 11. This shaft as .shown in Fig. 2 has-arms carrying a rod 251 which passes below all of the zero plungers 37 for all of the banks of value keys and is thereby adapted to lift the zero plungers out of the path of movement of shoulders 38 on segments 39 when shaft la is rocked by the action of cam arm 217 fast to the lever 131. The rod 251 also passes in front of extensions 255 of key detents 256. In this manner the zero plungers are withdrawn from stopping position of the differential 1nechanism so that it mav'operate on total printing operations and at the same time the value keys are locked. in their outer positions as detent 256 cannot be moved downwardly. The lever 131 has a second means for rocking shaft 11 for the purpose of pre-' venting the depression of value keys when the lever is being moved from one position:

to another or is in some 'position intermediate of its fi e intended positions; These five positions are determined by notches 24:4 in a fixed plate 245. A pawl or thumb grip 2&3 pivoted to lever 131 has a shoulder 242 for entering the notches 244. A plate 259 at the rear of pawl 243 and in the same vertical plane as a bent shoulder 263 of the pawl, is carried by a pair of arms 260 and 261 hung from pins 262 on the frame of the machine. A. spring 2(Sl is extended between arm 261 and a pin on the machine frame and this spring, through the plate 259, serves to urge pawl 213 into engagement with one of the notches in plate 2&5. The arm 260 carries a pin 265 extending through a slot in a link 266 pivoted at its upper end to a short arm 267 fast to shaft 14.

To adjust lever 131 from one position to another necessitates forcing the pawl or thumb grip 213 toward the lever and thus disengaging its shoulder 212 from one of the notches in plate 215. 'The rocking movement of pawl 243 forces plate 259 rearward and holds t-heplate in such position while the lever 131 is being adjusted and shoulder 263 of pawl 213 rides on the outer edge of plate 259. When the lever 131 comes to rest and pressure on pawl 213 is discontinued, spring 261, through arm 261, urges plate 259 forward, thus causing the pawl to reengage one of the notches 21%.

The rearward movement of plate 259 in I causing arm 260 to rock rearward, fumes link 266 upward and thereby,throu9;h the arm 267, rocks shaft 11 in the rope-.1 direction for causing rod 25% (Fig. to bepost tioned to prevent the depression value kevs by preventing movement of their detents 256, but when the pawl 243 is per-- mitted'to resume its normal position the rod 25-1 returns to its normal position through a reverse operation of the above described connecting mechanism under the action of spring 261. Thus the thumb gr p or pawl 213 and its connections to rod i i are operative to prevent a depression "f value keys only when the pawl is disengage i from one of the notches in plate 2 15.

It was previously described how the depression of a department key 21 (Fig. 5) results in a clockwise rocking of arm 16 and frame 29 (Fig. 2). This rocking movement.

is employed to lock lever 131 against manipulation so that it cannot be adjusted during an-operation of the machine. For this purpose frame 29 is connected by a sleeve surroundin shaft 1 1 to an arm 26S fast to the sleeve. This arm has a bent extension 269 which, when the sleeve rotates slightly on the depression of a department key, moves above a shoulder 270 on plate 259. It is therefore impossible'to force the plate inwardly and upwardly around the the totalizing capacity of the adjust mechanism for controlling total and subtotal printing operations, and for this purpose extends downward and rearward from its pivot 61 and at its rear end carries a rod 129 by which certain pitmen may be selected to control the engagement of totalizers with actuators by which the totalizers may be reset. The construction and operation of these pitmen will appear ,farther on.

Differential mechanisms-The differential mechanism consists mainly in a plurality of segment gears 39 (Fig.2) one of which is provided for each denomination included in machine. There'would therefore be one segment for each amount bank of keys and such extra ones as are required to make up th full number of denominations represented in the .totalizersl The segments 39 in design and operation are as'shown and described in the before mentioned Kettering and Chryst ap plications. Each segment (Figs. 2 and is pivoted to a pin 41 extending from the side of its corresponding key frame 24. and

also on each pin 41 is pivoted a. pair of segment rac s 107 and 108 which are connected to segments 39 by pins 1511 on the segments 39 passing through short slots 151 in the segment racks 107 and 108. These slot and pin connections permit the segment racks to move one 'unit relatively of the segments 39 for the purpose of accomplishin carrying operations. Each segment is provided with ashoulder 38 for cooperating with the shanks of keys and thereby regulating the movement of the segments. Each segment is also connected'by a spring 10 to a rod fixed at the rear of the machine. A rod 12 passing below the segments normally retains them in the position in which they are shown in the drawings. This rod is carried by a pair of arms 13 (Fig. 5) pivoted on studs 41 and having rollers 45 at their rear ends extending through aws 46 in bell crank levers 4T journaled on shaft 8 and in turn having rollers 18 extending into cam grooves 49 in disks 50 fast to drive shaft 1.

On the depression of value keys the zero stops 37 are moved out of the paths of shoulders 38, as previously described. permitting the segments 39 to rock in a counterclockwise direction under the action of their springs 40, but the velocity of the segments is regulated by rod 12 which is driven downwardly by the action of camsaQ -operating on roller 48 first to rock bell crank levers 47 in a clockwise direction and thereby cause the frames clockwise direction. The segments therefore follow rod 42 until their shoulders 38 engage the shanks of depressed keys. In this manner the rack segments 107 and 108 are differentially set and on the return movement of segments 39 are caused to actuate their respective' totalizing devices. The return movement of segments 39 is caused by the return of rod 12 to normal position as driven by its connections to cams 50. i

To insure accurate alinement of the segments 39 when in their differentially ad justed positions, so that totalizers may be properly engaged with racks 107 and 10S, pawls 06 are provided, pivoted on arms 67 secured to a shaft 68. Fast to shaft 68 is a downwardly extending arm 70 (Fig. 5) provided with a pin 73 passing through a slot in the pitman T2 pivoted at its rear end by a pin 74 to hell crank lever 17. A spring 69 is extended between pin 73 and a pin 71 on pitman 72. In operation the spring. 69 normally holds shaft (38 in such angular position that the pawls engage alining teeth 391 (Fig. 3) on segments 39, but when the segments are at rest in their moved positions the clockwise rocking of hell crank lever 47 forces pit-man 72 forwardly and thereby releases tension 'on spring 69 and the continued movement of the pitman 72 causes the shaft 68 and its arm 67 to rock in a clockwise direction and thereby engage pawl 66 with the alining teeth 391. ,The slot T5 in pitman 72 prevents the pitman from positively engaging pin T3v on arm TO until rod 12 nearly reaches its lowermost position and for this reason the pawls serve to check vibration of the segments previous to their positively alining and locking the same through the rear edge of slot T5 engaging pinsupporting pawls G6 are provided with pins 661 to prevent the pawls from rocking counter-clockwise. This is to safeguard against slow action of the segmentdriving springsiO. Springs 10 in becoming aged and sluggish in. their action might fail to drive the segments 39 the required distance before pawls-GO are engaged therewith; consequently if the pawls would not permit the required stroke of segments 39. an incorrect entry would result. By providing these one-way pawls the segments may continue to lower after the pawls have. been rocked in engagement therewith. but the pawls still serve to prevent rebound of the segments when their shoulders 38 strike depressed keys.

The particular alining devices provided in this invention are thought to be ofcon siderable importance totypes of account- 13 to rock in a counter-' (36 do not.

The arms 67 ing machines wherein the differential actuators are spring driven, as no dash pots or other protecting devices are required, on their account, to limit the speed of opention of the driving mechanism. It will be understood that .springs in accounting machines, asa rule, require that considerable time be provided for their operation, and

accordingly dash pots or spring controlling devices are provided to prevent excessive speed of the driving mechanism. By this simple change in alining devices which the present invention provides, the necessity for considerable controlling mechanism for the driving mechanism is eliminated. The segments 39 also have connections for determining the setting of the type-carriers in the printing mechanism; (Figs. 2 and 5). These connections consist of a plurality of beams 51 pivoted to the segments by pins at one end and at their opposite ends pivoted toarm 90' loosely journaled on shaft 8. and

. groove 92 in disk 50.

liQCtlQn cams 85 are rocked rearwardly.

' before which has a roller 91 extending'into a cam Through this conwhen segments 39 are at rest, into engagement with rollers 87 of such of the beams 51 as have been displaced from normal position and as segments 39 are locked in adjusted positions, as above described, beams 51 are compelled to rock around their pivots 52 by the action of cams 85. This movement in direction depends upon the extent of forward rocking of segments 39 and the adjustment of beams 51 on the preceding operation of the machine, and likewise the extent of their movement corresponds-to the difference between these two movements. Thus the rear or lower ends of beams 51 are finally adjusted to positions which correspond with the adjustment of their segments 39 and accordingly, through their connections to the type carriers, the latter are properly adjusted backward or forward from their preceding settings as required.

Toztzlizensu-The totalizing devices 1053 and 106 (Fig. 3) are adapted to be mesh-ed with and operated by the segment racks 107 and 108. v

The main totalizer 105 is described in the mentioned patent application of Kettering and Chryst, Serial No. 451,446, andfof the purposes of the .present application it is'thought necessary only to point out that it comprises a plurality of pinions which are journaled on a rod carried by a frame 109 which is secured-to a, rod. 111.

This rod is journaled in the side frames of the machine and carries an arm 113 (Fig.

end over shaft 1 and is also provided with a slot- 132 through which passes the rod 129 on total lever 130. The pitman is further provided with a slot 136 through which passes a pin 137 extending from a lever 140,

The lever 1-l0 has a journaled on shaft 3. roller 143 extending into groove 145 in cam disk 133. The cam groove in cam disk 133 is such that on rotation of drive shaft 1 lever 140 isrocked at the required time to. through the pitman 125. lever 119, arm 113, and shaft 111, rock the totalizer carrying frame 109 so that the totalizer will be held in mesh with the actuating racks 107 during their return stroke.

The department totalizers 106 are journaled on a rod 158 carried by a frame 110 journaled on shaft 112 but rockable therewith for the purpose of engaging the totalizer with actuating racks. As the frame 110 is connected by ball bearings to a frame 157 pinned to the shaft 1.12 the ball bearing connection between the frames permits relative horizontal movement for the pun pose of differentially positioning frame110 while compelling both frames to rock in a vertical plane when shaft 112 is rocked. The shaft 112 carries rigidly an arm 114 Fig. 9) having a roller 116 extending through an eccentric slot 118 in a lever 120 pivoted to a pin 122. The lever 120 carries a shortrod-12l,which passes between shoulders 128 of the pitman 125 which. as previously stated, is reciprocated by cam 133. The movement of the pitman through the lever 120 and its eccentric slot operating on pin 116, thus rocks arm 11% and the shaft 112 to engage a department totalizer with the actuating racks 108 and to hold the totalizer in engagement with the racks during their return movement. In this manner a selected one of the department totalizers is rotated to receive amounts of transactions. v a

The supporting frame 110 for the department totalizers 106 is provided with races 152 and 153 for ball bearings 151 resting between them and races 155 and 156 in a frame 157 fast to the totalizer supporting shaft 110. The totalizer pinions 106 are denominationally grouped on the shaft 158, as described in the Kettering and Chryst application No. 376,830, and are sufficient in numher to constitute four totalizing devices corresponding ;tothe. four department keys. Thus by shifting frame 112 along frame 157 any one of the totalizers may be brought into operative relation with racks 108 and at most it is only necessary to shift the 1 frame the distance between four totaliz'er pinipns 1111117101 to bring any totalizer into operative. position.

. "It was previously pointed out how the department keys serve differentially to. p'osition the totalizer carrying frame 110 along the guide frame meshes with a rack 172 fast to frame 110. A spring 160 (Fig. 4) normally urges the frame 110 to the right so that a certainset will be accurately positioned into the same;-

vertical plane with the actuators and maintained in this plane during the. rocking movement of the totalizer frame. For this purpose the segment ,8) and the rack 173 are respectively pro vided with alining teeth 17 5 and 176 for engagement by an alining device 177 (Figs. 1 and 2). This device is fast to a shaft 178 carrying rigidly an arm 179 pivoted at its upper end to a pitman 180 supported by drive shaft 1 and having a roller 181 extending into a cam slot 182 in a cam fast to the'drive shaft. At the beginningof rotation of shaft 1 the cam becomes operative to shift thevpitman rearwardly and thus engage the .alining device 177 with the teeth 17 5 and 176. \Vhen the-totalizer frame 110 is rocked to engage the totalizer and the segments, the rack 17 3 is consequently carried downwardlyout of mesh with segment 170 but it is retained in the same vertical plane by the 'alining device 17 7-Which is provided with a curved alining tooth 183 for this purpose. The alining device is not again disengagedfrom the segment 170 and rack 173 until after the totaliZer and its carrying frames 110 and 157 are rocked to carry the totalizer out of mesh with the segments, which movement again connects rack 173 with segment gear 170.

The keys are released and the alining device 17 7 withdrawn simultaneously after the reengagement of rack 17 2 with the segment 170. The totalizer frame 110 immediately slides along shaft 112 to its normal position under the action of spring 160, that 1s, of course, if it has been shifted during the operation of the machine, otherwise when the uppermost one of the department keys is depressed the rocking and alinement of the totalizer is the same but it has no longitlwnnal mov ment alon shaft 112.

157 by differentially oscillating the segment gear 170 (Fig. 8) which This gear 170 (Figs. '2 and- 'merly has been operated The transfer mechanism for the totalizers is the same in principle as such mechanism as described in the before mentioned patent application of Kettering and Chyr'st No. 4451,4146. To accomplish transfers, racks 107 and 108 (Fig. 3) have a movement relative to their respective segments 39 so that they may rotate their respective totalizer pinions one extra unit further than is determined by the differential movement of their companion segments 39. Each totalizer. pinion carries a pin 146 by which it may trip a transfer pawl 147 out of the path of a pin 118 on the segment rack 107 or 108 of next higher order, thereby permitting the rack to move the required extra unit under the action of 'a .spring 1 19 extended between it and an arm 150 of the segment 39.

A single set only of transfer devices is provided for the multiple totalizers and these are loosely pivoted on a shaft 187 mounted in the side frames of the machine, and are in such planes as to be operative only in connection with the particular totalizer in operative relation with the differential mechanism.

The above application No. 151,146 also describes the construction and' operation of restoring devices 297 for the transfer mechaanism. These devices are permittedto operate at their required time and are then .restored by an oscillating rod 298 carried by a pair of arms 299 which in the present case are controlled in their operation by cam .300 fast to shaft 1 and constructed to reciprocate a pitman 301 connected through an intermediate-arm 302 to the rod carrying arms 299, and by link 303 to the restoring mechanism for the department totalizers.

The mechanism for restoring the transfer device in the present case has a. different time of operation than the mechanism in the application above referred to and also in other accounting machines wherein similar oscillating actuators are employed. Forthe transfer devices were restored at the beginning of operations of the machine, but in the present case-they are restored at the end of operations, consequently in total printing no preliminary operation of the machine is required for the sole purpose of restoring the transfer mechanism. To more fully explain this matter, theoperation, in general, in this type of machine, of the different1 1 segments on adding and totalizing operations will be briefly pointed out.

In adding operations the segments move down the required distances and when at rest in their lower positions the totalizing devices are meshed therewith. On the return of the segments the totalizers are rotated thus causing possibly some of the transfer devices'to be tripped and permitting the racks carried by the segments to move the extra unitf0r effecting carrying operations.
